Hi All,
I saw some information about FDE on ubuntu core 20/22. I follow the steps from document(https://ubuntu.com/core/docs/full-disk-encryption).
Add this to model assertion
{
…
"grade": "signed",
"storage-safety": "prefer-encrypted",
…
}
My disk still not encryption.
I saw “External I2C/SPI-based TPM modules are not currently supported.” in document. My device is SPI-based TPM.
Is this the reason for failure?
Is there any solution to encrypt disk without TPM?
